Perhaps the easiest way to do this would be to use a video editor (Adobe, DaVinci, etc) and synchronize the TN1 video to the Puggo video. Inserting black frames or duplicate frames or whatever other tricks you want to try to pull, as needed.

Put the two video tracks into different layers. You can minimize the puggo one and put it in the corner or something. Get the first “Star Wars” frame to occur at the same frame timing as the first “Star Wars” frame of puggo. And then continue on through the film, finding the next time that the first frame of a shot no longer matches up. And then fix it. Export your video and mux it with the puggo audio.

The alternative would be to do similar alignment, but bringing Puggo to sync with TN1, instead of the other way around, making sure that the audio is cut when the video is cut. And then applying crossfades or whatever you need to do to make it sound okay. Then, export the audio. I’m not familiar enough with puggo’s 16mm to know what it is missing, etc, though.

Either way, the point is that you have the Puggo audio synched to the Puggo video, so the trick is to synchronize based on the two video tracks you have because it can be done precisely that way.
